Abstract

The invention relates to a double-liquid screw valve capable of accurately controlling flow, and belongs to the technical field of machinery. The invention provides a double-liquid screw valve capable of accurately controlling flow. The double-liquid screw valve comprises a first monitoring module used for monitoring glue input flow, a second monitoring module used for monitoring glue mixed flow, a third monitoring module used for monitoring glue output flow, and a control module used for receiving signals transmitted by a first signal transmission module, a second signal transmission module and a third signal transmission module, controlling the rotating speed of a first rotor and the rotating speed of a second rotor by controlling a first driving device and a second driving device, and then controlling the pumping-out amount of liquid in a first inner cavity and the pumping-out amount of liquid in a second inner cavity. Through the combined action of the three monitoring modules and the control module, closed-loop monitoring and control of the whole glue input, mixing and output processes are achieved through the double-liquid screw valve.

Description

technical field [0001] The invention relates to a double-fluid screw valve capable of precisely controlling flow, and belongs to the technical field of machinery. Background technique [0002] In industrial production, dispensing is required in many places, such as integrated circuits, semiconductor packaging, printed circuit boards, color LCD screens, electronic components, auto parts, etc. Most production scenarios only need to use a single glue for dispensing, but some production scenarios need to mix two different glues according to a specific ratio. At this time, the precise control of the glue mixing ratio is very important to ensure the production quality . [0003] The double-liquid screw valve is a dispensing valve that can realize automatic glue mixing and dispensing. However, the existing two-liquid screw valve lacks a flow monitoring module or the flow monitoring module has low precision, and cannot accurately monitor the mixing ratio of the glue, which also le...
